Hmm, I stopped opening chests before the entrance to Durance 3. That could have been a mistake. On the other hand, since I heard that others got Tal's armor from the armor rack in Durance 3, I always check it, but I never found anything useful so far.

I once found a 5% BK ring in a standard chest in Durance 3. That's around 2 years ago, however. The best I got in 1.10 was a Pul rune (chest behind Meph).

I got a Lo rune and a 150 psn dmg small charm from the chest behind meph. Usally, because there's so many little piles of gold there, you can't see all the items that pop out. NEVER JUST ASSUME NOTHING DROPED! Just pick up the gold and drink the potions, something's bound to show up.
